ValueAnimator 使用注意事项

Posted 2021-01-18 cnmly

1、动画时间：如果是xml定义的值，需要使用getResources().getInteger(int)获取值

2、动画重复次数：Integer.MAX_VALUE 改为Integer.MAX_VALUE>>2

 

mIconAnimator = new ValueAnimator();
mIconAnimator.setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));
mIconAnimator.addUpdateListener(
        new ValueAnimator.AnimatorUpdateListener() {
            @Override
            public void onAnimationUpdate(ValueAnimator animation) {
                int rotation = (int) animation.getAnimatedValue();
                Log.e("OkHttp", "rotation=" + rotation);
                ivButtonIcon.setRotation(rotation);
            }
        }
);
mIconAnimator.setRepeatCount(1);
mIconAnimator.setInterpolator(new AccelerateDecelerateInterpolator());

mIconAnimator.cancel();
int from = (int) (ivButtonIcon.getRotation() % 360f);
int to = reset ? 0 : 90;
if (from == to) return;
mIconAnimator.setIntValues(from, to);
mIconAnimator.start();
